Senior .NET Software Engineer / SRE

About the Project: This is an ongoing multi-year digital transformation initiative (now roughly 2+ years in) focused on modernizing financial services platforms, making them more scalable, reliable, automated, and cloud-native. The .NET Engineer / SRE will be building and extending tools / frameworks for SRE practices, including automation scripts, custom monitoring, CI/CD enhancements, reliability tooling, etc. The .NET Engineer / SRE will help bridge the gap between development teams (writing .NET) and SREs (ensuring reliability at scale), especially within this strategic / tool building-focused SRE practice. This is not a traditional .NET Developer (no owning user-facing APIs or business logic for financial services), but rather applying .NET skills to SRE tasks, including building custom tools for automation, reliability, and release engineering, creating GITHub Copilot context files to embed SRE practices (security / performance checks) early in development cycles, debugging / refactoring code in production environments, performing root-cause analysis, and iterating post-deployment. Additionally, there’s no traditional on-call production monitoring / support, whereas the focus will be on design, architecture, automation, and enabling scalable DevOps / SRE practices for development teams, rather than day-to-day firefighting., * .NET Core Development (hands-on core expertise) - Strong C# / .NET (Core 6/8+) Development | Building / Maintaining Production-Grade Applications / APIs / Services | Clean / Maintainable Enterprise Code | Design Patterns (Factory / Singleton, etc.) | Onion / Clean Architecture

• Cloud Modernization / Migration - Migrating Legacy .NET Applications to Cloud-Native Azure Architectures

  Refactoring / Modernizing Existing Codebases While Maintaining High Uptime (99.9%+)

• Azure-Native Application Development - Designing / Deploying / Supporting .NET Applications Directly in Azure with Real Production Workloads

  Beyond Portal-Based “Click-Ops”

  Deep Integration of Azure Services into .NET Code

• AKS / Containerization - Containerizing .NET Applications (Docker Multi-Stage Builds)

  Deploying / Managing within AKS (Deployments / Services / ConfigMaps / Secrets / Helm / Node Pools/ Autoscaling / Ingress / Cluster-Level Troubleshooting)

• CI/CD / Release Engineering - Building / Maintaining YAML-Based CI/CD Pipelines in Azure DevOps

  Automated Builds / Testing / Security Scans / Docker Image Creation / Deployments to AKS / App Services

  Blue-Green Deployments / Feature Flags for Zero-Downtime Releases

• Azure Platform Services Integration - Integrating Core Azure Services into .NET Applications (App Services / Azure Functions / Service Bus / Event Grid / Azure Monitor / Application Insights with Custom Telemetry / Distributed Tracing / Metrics)

• IaC / Terraform - Developing / Managing Terraform-Based Infrastructure (AKS / VNETs / Private Endpoints / Service Bus / SQL Database / Storage) Aligned with Application Development

  Scripting (PowerShell / BASH / Python)

  Developer-First Mindset for Building Automation Tools / Reliability Frameworks

Ideal Senior Candidate: The ideal candidate will come with a Developer-First Mindset for full SDLC, Architecture Ownership, and Problem Solving (build the tool if it does not exist approach). Having .NET fluency enables strategic SRE in their .NET / Azure ecosystem, bridging gaps between development and operations without siloed roles. The Senior Engineer MUST be able to walk through their most recent projects, in depth, describing complex features, debugging, and development frameworks (why you’d choose one over the other for particular tasks, etc.)., * Azure Governance / Best Practices - Azure Policy / GitHub Copilot Context / Embedding SRE Practices Early in Development Lifecycle
